2005 Mercury Mariner Question: 4x4 will not work only the front wheels pull and not the back 4x4 light blinks

4x4 will not work only the front wheels pull and not the back -
Answer 1
The 4X4 light flashing indicates a fault in the transfer case system. The concern could be electronic or mechanical. We do not see many problems with this system. It takes a scanner that can access the 4X4 module to pull DTC's. Without these codes, it would be impossible to diagnose. -
